• Question 452:

  In which way does a spine-and-leaf architecture allow for scalability in a network when additional access ports are required?

  A. A spine switch and a leaf switch can be added with redundant connections between them.
  B. A spine switch can be added with at least 40 GB uplinks.
  C. A leaf switch can be added with connections to every spine switch.
  D. A leaf switch can be added with a single connection to a core spine switch.
  C. A leaf switch can be added with connections to every spine switch.

  Spine-leaf architecture is typically deployed as two layers: spines (such as an aggregation layer), and leaves (such as an access layer). Spine-leaf topologies provide high-bandwidth, low-latency, nonblocking server-to-server connectivity. Leaf (aggregation) switches are what provide devices access to the fabric (the network of spine and leaf switches) and are typically deployed at the top of the rack. Generally, devices connect to the leaf switches. Devices can include servers, Layer 4-7 services (firewalls and load balancers), and WAN or Internet routers. Leaf switches do not connect to other leaf switches. In spine-and-leaf architecture, every leaf should connect to every spine in a full mesh.

  Spine (aggregation) switches are used to connect to all leaf switches and are typically deployed at the end or middle of the row. Spine switches do not connect to other spine switches.

• Question 453:

  Which port state processes BPDUs, but does not forward packets or update the address database in Rapid PVST+?

  A. blocking
  B. learning
  C. listening
  D. disabled
  A. blocking

  ---

  Blocking State

  A LAN port in the blocking state does not participate in frame forwarding.

  A LAN port in the blocking state performs as follows:

  Discards frames received from the attached segment.

  Discards frames switched from another port for forwarding.

  Does not incorporate the end station location into its address database. (There is no learning on a blocking LAN port, so there is no address database update.) Receives BPDUs and directs them to the system module.

  Receives, processes, and transmits BPDUs received from the system module.

  Receives and responds to network management messages.

• Question 454:

  Which WAN access technology is preferred for a small office/home office architecture?

  A. broadband cable access
  B. frame-relay packet switching
  C. dedicated point-to-point leased line
  D. Integrated Services Digital Network switching.
  A. broadband cable access

  ---

  Service providers provide Internet access using broadband services such as DSL, cable, and satellite access. Broadband connections are typically used to connect small offices and telecommuting employees to a corporate site over the Internet. Data traveling between corporate sites over the public WAN infrastructure should be protected using VPNs.

• Question 455:

  An engineer has configured the domain name, user name, and password on the local router. What is the next step to complete the configuration tor a Secure Shell access RSA key?

  A. crypto key Import rsa pem
  B. crypto key pubkey-chain rsa
  C. crypto key generate rsa
  D. crypto key zeroize rsa
  C. crypto key generate rsa

  ---

  The next step to complete the configuration for a Secure Shell (SSH) access RSA key on the local router is to use the "crypto key generate rsa" command. This command generates an RSA key pair that will be used for SSH encryption and authentication purposes.

  After running this command, the router will prompt for the key modulus size (usually 1024 or 2048 bits) and will generate the RSA key pair. The generated RSA public key will be used for SSH server authentication, and the private key will be stored on the router for secure SSH communication.

• Question 456:

  Refer to the exhibit. For security reasons, automatic neighbor discovery must be disabled on the R5 Gi0/1 interface.

  

  These tasks must be completed:

  1. Disable all neighbor discovery methods on R5 interface Gi0/1.
  2. Permit neighbor discovery on R5 interface Gi0/2.
  3. Verify there are no dynamically learned neighbors on R5 interface Gi0/1.
  4. Display the IP address of R6’s interface Gi0/2.

  Which configuration must be used?

  A. R5(config)#int Gi0/1 R5(config-if)#no cdp enable R5(config-if)#exit R5(config)#lldp run R5(config)#no cdp run R5#sh cdp neighbor detail R5#sh lldp neighbor
  B. R5(config)#int Gi0/1 R5(config-if)#no cdp enable R5(config-if)#exit R5(config)#no lldp run R5(config)#cdp run R5#sh cdp neighbor R5#sh lldp neighbor
  C. R5(config)#int Gi0/1 R5(config-if)#no cdp run R5(config-if)#exit R5(config)#lldp run R5(config)#cdp enable R5#sh cdp neighbor R5#sh lldp neighbor
  D. R5(config)#int Gi0/1 R5(config-if)#no cdp enable R5(config-if)#exit R5(config)#no lldp run R5(config)#cdp run R5#sh cdp neighbor detail R5#sh lldp neighbor
  D. R5(config)#int Gi0/1 R5(config-if)#no cdp enable R5(config-if)#exit R5(config)#no lldp run R5(config)#cdp run R5#sh cdp neighbor detail R5#sh lldp neighbor

  ---

  Disable all neighbor discovery methods on R5 interface Gi0/1

  (config-if)#no cdp enable / (config)#no lldp run

  Permit neighbor discovery on R5 interface Gi0/2.

  (config)#cdp run

  Verify there are no dynamically learned neighbors on R5 interface Gi0/1.

  #sh lldp neighbor (just to confirm LLDP discovery has been disabled)

  Display the IP address of R6's interface Gi0/2

  #sh cdp neighbor detail ("detail" shows information such as IP address)

• Question 457:

  DRAG DROP

  Drag and drop the IPv4 network subnets from the left onto the correct usable host ranges on the right.

  Select and Place:

  

  

• Question 458:

  What is the purpose of the ip address dhcp command?

  A. to configure an Interface as a DHCP server
  B. to configure an interface as a DHCP helper
  C. to configure an interface as a DHCP relay
  D. to configure an interface as a DHCP client
  D. to configure an interface as a DHCP client

  ---

  This command enables the DHCP client on the interface and removes all manually-configured addresses on the interface. https://www.cisco.com/c/en/us/td/docs/routers/nfvis/switch_command/b-nfvis-switch-command-reference/ip_addressing_commands.pdf

• Question 459:

  Why would an administrator choose to implement an automated network management solution?

  A. to reduce operational costs
  B. to support simpler password policies
  C. to enable "box by box" configuration and deployment
  D. to limit recurrent management costs
  A. to reduce operational costs

• Question 460:

  Refer to the exhibit.

  

  The administrator must configure a floating static default route that points to 2001:db8:1234:2::1 and replaces the current default route only if it fails. Which command must the engineer configure on the CPE?

  A. ipv6 route ::/0 2001:db8:1234:2::1 3
  B. ipv6 route ::/128 2001 :db8:1234:2::1 3
  C. ipv6 route ::/0 2001:db8:1234:2::1 1
  D. ipv6 route ::/0 2001:db8:1234:2::1 2
  A. ipv6 route ::/0 2001:db8:1234:2::1 3
